DIY reversible plow for a mini tractor

A plow is a labor tool designed for plowing hard soil and has been used by man since ancient times. The intended use of a plow determines its technical and quality characteristics: the design of the frame and cutting element, fastening mechanisms and stops, material of manufacture and its thickness.

General characteristics

There are several types of plows according to their purpose:

manual - for plowing soft land of a small area;
horse-mounted - used in situations where it is necessary to cultivate land, access to which is limited for special equipment;
with rope traction - helps to cultivate the soil in hard-to-reach places, for example, in the mountains or in a swamp;
mounted – works in conjunction with special equipment, allows you to reduce the turning radius during sequential plowing;
trailed – general purpose plow.

The mentioned types of plows, in turn, are divided into the following subspecies:

single-hull;
double-hull or more;
disk - reversible;
rotary.

The generally accepted configuration of a plowing tool, which you can construct with your own hands, is shown in Figure 1.

The main parts of the hull structure have the following parts:

chisel – pad on the cutting part;
ploughshare – removable “knife”;
wing, chest and blade feather;
uglosnim – cuts corners from layers of soil;
stand – fastening element.

Modern technologies make it possible to make a plow with your own hands. You can design it according to your drawings or modify a ready-made one to suit your needs. A tool made independently has a number of advantages and characteristic design features.

Various plow designs

First you need to decide on the design of the device, because there are several different types.

Cylindrical

The cylindrical type of the plow is distinguished by its excellent versatility, because it is suitable for almost any type of soil and field size. This shape allows you to cope well with crushing soil. In addition, making such a unit yourself will not be a problem.

Cylindrical

The only drawback of this design is its shallow penetration into the ground.

Half-screw

If you do not need to loosen the soil, but only need to raise layers of soil, then the semi-helical shape of the working part of the plow would be an excellent option. It penetrates deeply into the ground, but at the same time practically does not create a loosening effect. It is usually used for heavy soil.

Lemeshny

There are also plowshare plows, but they are quite difficult to make with your own hands, so they are not worth considering.

Features of a homemade model

A plow assembled with your own hands is a tool that meets target needs and has a low cost. To assemble it, you can use materials available, as well as parts of the structures of other agricultural units. The latter can be taken from old agricultural workshops, ferrous metal collection points, and other similar places.

A homemade plow can be easily adjusted to suit your needs. It is possible to adapt it to different types of soil, draft mechanisms, and even to the functions of processing agricultural crops. Your own plow can be manufactured taking into account the power and productivity of tractor equipment, which will allow you to achieve the highest efficiency and reduce destructive loads on the plowing tool.

The cutting element of this plow can be replaceable and manufactured/sharpened independently, which significantly reduces the cost of servicing the mechanism. With independent production, it becomes possible to vary the intended use - introducing the function of replaceable elements: nozzles, fasteners, parts of the body and frame. This allows for combined work, such as plowing and mowing bushes.

When making your plow, you can pay special attention to the choice of materials and their quality. This is one of the key advantages of homemade assembly, since when buying a plow in a store, it is difficult to be sure of the quality of the metal used to manufacture the factory unit. After purchasing a store model, you may need to further refine it or replace some low-quality structural components.

Comparison of factory and homemade plows

We will select for analysis attachments for a mini tractor with a skimmer, sold in Moscow and made with our own hands (prices for self-assembled consumables, analogues of purchased ones).

Model	price, rub.	Price for self-assembled (consumables), rub.
Double-furrow plow 1L-220, country of origin: China	25 700	15 000
Double-furrow plow CR-M15, country of origin: Russia	27 900	16 000
Double-furrow moldboard plow, Chelyabinsk	22 000	10 000
Plow 2-hull, St. Petersburg	45 000	17 000
Wirax double-furrow plow, country of origin: Poland	34 000	15 000

From the presented table it can be seen that the price of a factory unit ranges from 25,000 to 45,000 rubles.

Making a plow with your own hands in the most expensive scenario will cost half as much. This is achieved by using scrap materials and parts from broken down agricultural machinery, which are abundant in the villages of our country.

Materials and tools

Making a homemade plow for a mini-tractor requires the following basic tools:

And an additional tool, the list of which is determined by the design of a particular mechanism and the conditions of its production.

The materials making up the main structure must be solid steel blanks. Violations of their integrity - cracks, deformation, severe rust - are unacceptable.

List of materials that may be needed:

thick-profile sheet metal of high strength;
metal corners and plates of sufficient thickness;
bolts of various calibers;
additional items (washers, bearings, springs) determined by the characteristics of a particular design.

How to make a farm tractor from a LEGO constructor: instructions, diagram, description

Children really love to play with agricultural machinery, for example, a tractor, excavator, crane, etc. Therefore, it is not surprising that many are interested in the question “How to make a tractor from Lego?” Because assembling a toy yourself is a great activity for all kids, and then they can also play . If you attach a trailer or bucket to the tractor, the game will become even more interesting.

Making an agricultural tractor is also easy; to do this, follow these instructions:

Attach the 2*4 shape to the top of the small wheels.
Attach a 2*10 plate on top.
Attach large wheels to the back of the structure.
Attach 2 parts to the 2*4 plate: trailer, 1*2 shape, attach to the bottom of the large wheels, so that the part with the hook protrudes.
Attach a 3*2 plate to the 2*8 piece and attach it to the top of the structure.
Connect the headlights to the fenders and place them on the front of the tractor.
Connect 2 parts 2*3 and a plate 2*2, so that the latter remains at the bottom, and place it in the upper front part, it should coincide with the wings of the tractor.
You need to place a 2*2 cube nearby.
Take two 1*2 pieces with two holes inside and attach them next to the previous piece.
Attach the hood and place smooth plates on the rest of the part.
Place 3 parts on a 4*4 mold, leaving a passage and attach to the back of the structure.
Place windows in the cabin and close the gaps with 1*1 parts.
Place a windshield in front.
Make the roof from a 4*4 piece.
Make a pipe for a tractor.
Take 2 4*1 cubes with three holes and place them on the sides of the roof.
Attach the bucket.

Tractor with bucket

More detailed instructions are presented in the video. You can optionally attach a trailer to such a tractor; it can also be made from Lego bricks.

And also, many designers allow the child to make not only the transport itself, but also the driver. The figure of the tractor and its contents, color, etc. can be very different, it all depends on your imagination.

How to do it?

In order to facilitate the process of assembling a plow for a mini-tractor, you can go by reconstructing another tool of the same name, used in conjunction with draft objects: a horse-drawn plow or a skimmer from the plowing mechanism of a large tractor.

Assembling the required unit requires drawing up the correct drawings. Their presence will ensure optimization of the design, reduction in the number of components, simplicity and quality of assembly.

The drawings should indicate the dimensions of the elements, which are closely related to the dimensions of the mini-tractor and the properties of the cultivated soil. During the manufacturing process, it is important to adhere to these parameters.

At the design stage, it is worth drawing separately each detail that has an irregular shape, respecting its natural size. In the future, from such drawings it will be possible to create a pattern for transferring the image of the part onto a metal workpiece. Some variations of the plow drawing are shown in Figures 2 and 3.

Let's consider two options for making a plow for a mini-tractor.

From a horse plow

This plow configuration, mounted with a mini-tractor, is considered the easiest to manufacture. All work on reconstructing a horse-drawn plow comes down to adapting to it a frame that has a special fastening mechanism, equipping it with a wheel (if necessary) and a weighting agent.

A horse-drawn plow consists of a body and a double-sided frame, which serves as a mechanism for attaching to the animal's harness and as a means of controlling the plowing process. Its simplest configuration is shown in photo 4.

In this case, it is necessary to reconstruct the mounting part of the horse-drawn plow into one that will be installed on a mini-tractor with the least effort. This process can be simplified by making a tow bar for a tractor mount. A copy of it is shown in photograph 5.

The towing device is easy to manufacture. A wide plate, which has two horizontal holes with internal threads at the edges, is complemented by a protrusion in the middle, into which a fork ball with a leg is screwed/welded. An L-shaped part is attached to the center of the plate, serving as a locking mechanism for the plow frame mounted on the tow bar. The plate is placed between the two “ears” of the tractor mount and secured with four bolts.

The modification of the horse-drawn plow shown in photograph 4 is equipped with a special wheel. It serves as a support for the structure frame; it can be used to adjust the depth of penetration of the plow into the soil.

Adjustment is carried out using a simple mechanism - a threaded bracket into which a clamping bolt is screwed. The wheel stand can move vertically inside the bracket. The bolt fixes it in the desired position. This design allows, if necessary, to move the bracket along the plow frame.

The wheel itself is made of a metal rim, spokes and an axle drum. To make it, you can use a 300x50 mm metal strip, reinforcing bars, or a piece of pipe with a diameter equal to the diameter of the wheel axle.

The metal strip is bent in the form of a hoop, its edges are welded together, the weld seam is ground with a grinder or cutting wheel of an angle grinder. A piece of pipe equal to the width of the tape is placed in the center of the circle. The distance from the rim to the outer surface of the pipe - drum is measured. The reinforcement spokes will be equal to this distance. The resulting blanks are welded together. To improve the torsion characteristics of the wheel, a bearing of the appropriate diameter can be welded into the drum. This will reduce friction and reduce the load on the wheel axle.

The described plow design can be operated in two ways. In the first case, a second person will be needed to control the plow from behind, adjusting the furrow line. In this case, the “manager” applies pressure on the frame necessary for sufficient immersion of the ploughshare into the ground.

In the second case, the presence of an assistant is not necessary. The plow becomes heavier and moves on its own. The load can be a piece of heavy metal or a stone enclosed in a frame. The weighting agent is placed on the edge away from the tractor. In this case, the pressure on the share will be maximum with the available weight. To prevent the load from overturning the plow, it should be secured on the underside of the frame.

When operating a plow without a second person, it is worth considering the factor of furrow curvature. The simplicity of the described design assumes that the plow “swims” from side to side. To eliminate this problem, it is necessary to equip it with a “hard” clutch with the tractor. In this case, the draft mechanism will straighten the furrow strip.

From skimmers

A skimmer is an element of a tractor plow that serves to cut off the top layer of soil during plowing. Photo 6.

Its shape is similar to the working body of a plow share, and its size is half the size. This fact allows you to effectively use the skimmer as a plow for a mini-tractor.

During the design process, you will need to weld a frame that will hold the skimmer and attach it to the tractor towbar, and also equip it with a stop wheel.

When creating drawings of this design, it is worth taking into account the power of the tractor, the condition of the cultivated soil, and the volume of future work. If you plan to plow a large area of land, you can use two skimmers on one frame. In this case, the plow will have a double body. This is necessary in order to reduce the load on one plowshare body and reduce its wear.

The process of assembling the structure and installing it on a tractor is similar to reconstructing a horse-drawn plow. A frame of a similar configuration, a wheel, fastenings for the ploughshare stand and the entire structure to the towbar are made. A weighting device or control handles are installed for manual correction of the furrow.

Description of frame assembly work

The frame is taken as the base - the guild, the drawing can be viewed below. You can make it from a piece of metal rectangular pipe with thick walls 52x40x7 mm. A fork is made for the support wheel. To do this, two wider walls are cut off on opposite sides.

The middle of the frame is marked; this is where the cross beam will be welded. In the same place, the rack-springs are attached using welding. The drawbar will be attached to them. There is a hole left on the front of the frame, the beginning of the fork. It should be welded tightly, otherwise during operation soil and debris will get into the hole and clog it. This will make it rust quickly.

There is also a hole at the back of the frame, which is welded with a rivet. A round hole of 11 m is drilled in the rivet. An M10 nut is first welded onto the rivet.

Plow shank attachment

Next, the plow stand is attached. To do this, a hole is drilled in the wide walls at the end of the pipe on both sides. It is made rectangular and has dimensions of 31x16 mm. The plow stand is attached here. The side walls (narrow) are also drilled through to a diameter of 10.2 mm. The handles will be attached here using M10 bolts.

Handles are made separately. To do this you will need a half-inch metal pipe. You can take it from an old plumbing system. The size and bend of the handles depends on the height of the person who will work with the plow.

The handles need to be made as follows. The pipe is flattened at both ends with a hammer. 10.2 mm holes are drilled into them and attached to the frame using bolts. For convenience, a waterproofing tape or rubber strip is wound on top. This will make it easier to hold the element with your hand when working.

It is necessary to give the structure additional rigidity. To do this, take the same half-inch pipe. It is welded as a cross member.

Making a drawbar and fastening a wheel

In order to make the drawbar, they also take an iron pipe.
To do this, take a piece and cut a thread on both sides. Using hinges, the pipe is attached to the springs of the frame strut. The connection is made through a special plug on the axle with welded nuts. The fork is also made from the same rectangular pipe, but they take a small piece and cut a channel out of it. A half-inch coupling should be secured to the channel walls. A long M10 bolt is used as an axis for the hinge. A tee with a hole through ? is mounted at the end of the drawbar. The thread in the tee is ground off and a piece of pipe is inserted, which is selected according to diameter and length. The wheel can be used from an old bicycle, but it will not withstand the load, so they only take rubber from it. The disc according to the diameter of the wheel is cut from a sheet of getinax with a thickness of 25 mm. A hole is drilled in the center of the wheel where a nylon hub-bearing will be inserted. A groove is machined along the edge for the tire. For the wheel axle, a long bolt with a diameter of M10 is also used.

Safety precautions

When operating a homemade plow, appropriate safety measures must be observed. Among them, the most important points can be highlighted.

while the plow is moving along the furrow, it is unacceptable to adjust it in height, clear the wheel and ploughshare from the earth and other manipulations associated with human participation;
all connection points must be securely fastened - play is unacceptable;
it is necessary to carry out timely cleaning of mechanisms and sharpening of cutting elements;
Perform all actions only with the plow immobilized and the tractor turned off.

To ensure labor safety, it is important to carry out work that meets the technical characteristics of a specific agricultural mechanism. Excessive loads can lead to rapid wear, damage to the unit and harm to human health.

To learn how to make a plow on a mini-tractor with your own hands, see the following video.

A plow for a mini tractor is necessary to cultivate the land before planting. The presence of the unit allows you to increase labor productivity. The stores offer a wide selection of agricultural tools, so homeowners will find equipment for their garden and vegetable garden. With its help, you can quickly cultivate large areas of land.

Mini tractors are suitable for garden work; they have attachments. By purchasing a plow, you can quickly plow the land and prepare it for planting.

Setting up a plow on a mini tractor

Today, many farmers use a tool such as a mini tractor to work on their land.

Of course, a mini tractor, like any equipment, has the ability to break down, and in order to prevent this, you must first use it correctly, as well as correctly configure the plow on the mini tractor.

Setting up a plow on a mini tractor is a rather labor-intensive process that requires special care. So, in order to adjust the plow on a mini tractor to a given depth for plowing, you must first deliver the mini tractor to a concrete site.

First, you need to set up the skimmers, since they will also be very actively used in the future during the work process. In order to adjust the skimmers, you will need to fix the skimmer using a cylindrical protrusion.

The edge of the skimmer itself must be parallel to the plane of the edge of the main body. At the very end of the setup, you will need to tighten the clamps that are used to attach the skimmer to the frame that the plow has.

After the skimmers have been adjusted, it will be necessary to adjust the plow itself. In order to do this, you must first place a wooden lining under the left wheels of the mini tractor.

The thickness of such linings should be 3-4 centimeters less than the plowing depth. The same pads will need to be installed under the plow wheel, which is the support wheel.

Then, using a screw mechanism, the plow is lowered onto the platform. In this case, you need to ensure that the plowshares fully touch the same area.

After this, the lateral movements of the plow are adjusted relative to the longitudinal axis of the mini tractor. To do this, you need to raise the plow so that the plowshares are approximately 2 - 3 centimeters above the ground.

The latest adjustments to the plow can be made directly at the work site, that is, in the field. During the first approaches, the processing depth is checked along with the working width. If transverse distortions are observed, they will need to be eliminated by adjusting the braces.

After all these processes have been completed, it will be necessary, of course, to check whether the plow is configured correctly - for this you will need to check the location of the plow towards the main draft. The limiting chains must be in a completely free state.

Types of plows

A plow for a tractor can be purchased ready-made, but it is possible to make it yourself. Tillage is a complex operation that is performed before sowing crops and after harvesting.

The models of plows are different, but they are united by their structure. The product has a ploughshare made of metal, which turns over layers of earth. The walk-behind tractor drives across the field, and the ploughshare follows it, turning over the top layer of soil and destroying the weeds. This happens because their roots are cut by the ploughshare, as a result of which the weeds end up deep in the ground after plowing. They cannot germinate and die.

During the plowing process, the soil is loosened, it becomes crumbly and saturated with oxygen. There are different types of plows, so when choosing a tool you need to take into account the area of land, soil type and other indicators, then the quality of land cultivation will be high.

Most common varieties

The plow can be of different types:

2-hull – characterized by maneuverability and ease of use (a double-hull plow can serve for a long time and provide large volumes of work);
disk - will provide reliability and withstand heavy loads;
single-hull – very light, ideal for seasonal work;
reversible - “active” plow, the parts in which rotate - a little heavy, but convenient and efficient in operation;
horse (or equestrian) – produced for working with “human” force, that is, with horses, but it is also easy to make yourself (for example, from a bicycle frame);
changeover plows provide not only stable operation, but also save fuel.

As you can see, the design thought does not dry out, and the variety of plows makes it possible to cover any needs of both the area and the workers. In addition, if you ask yourself how to properly adjust and how to set it up, devote some time to them, then you can get the ideal option for a particular case. Let us add that sometimes it is advisable to use a rotary option.

Disc plow

It is suitable for cultivating heavy soil in early spring. A disc plow is different in that it plows the ground but does not turn it over. The design consists of a front and rear frame, each of which is equipped with disk housings. Knives are installed in front, they make a ditch along which the discs move.

A support wheel is attached to the product; it is used to regulate the depth of plowing. Durable steel is used to produce cutting elements.

Reversible plow model

First of all, they are distinguished directly by the shape of the ploughshare, which in appearance resembles a bird feather. Due to the fact that its upper part is bent, the soil has the ability to turn over. Suitable for processing difficult soils.

This type of plow got its name from the peculiar way it tilled the soil. It's like he's wrapping her around. This technique is convenient for long lengths.

Rotary plow

The mechanism has several curved shares; manufacturers fix these parts on one axis. After turning on the mini tractor, the axle starts to move, it rotates and turns the soil. The unit can move not only in a straight line, but also in different directions. It plows the soil to a depth of 25-30 cm.

Plowing with a horse plow

Plowing is a process that requires the plow to cut away soil, rhizomes, vegetation, and gently turn side soil.

Basic requirements for plowing:

It is better to carry out plowing immediately after harvesting crops, while the soil retains enough moisture;
the turf layer is thoroughly wrapped and crumbled as finely as possible;
the surface is desirable to be continuous and dense, without the formation of voids or irregularities;
mineral fertilizers, manure and turf are completely plowed;
The furrows should be straight, or with a slight deviation from the norm, with a minimum gap between them.

The fundamental thing when plowing is to loosen the fertile layer, remove the turf and turn it around completely for further reheating to a state of humus.

Sometimes you have to deal with stones and other natural barriers that are too strong for one horse, so for increased resistance, two-horse and multi-horse teams are used. Medium and heavy-duty walk-behind tractors cope with this task quite simply.

Plowing with a walk-behind tractor

Plowing with a single horse

Plowing with one horse is quite a comfortable process, provided that the plow depth and width are adjusted properly. Only in this case, it goes exactly along the furrow, smoothly without additional resistance other than the rise of the ground. The horse moves at an even pace.

As a rule, the draft power of one horse is used on previously plowed areas, or on turfy, weed-free soil.

Cultivating the land with a horse-drawn plow with one horse

Plowing with steam horse harness

Heavy loamy soils, as well as virgin soil and areas where greater traction force is needed, use two-horse and multi-horse harnesses.

What does the harness consist of?

When harnessing horses together, the defining moments are:

competent selection of animals and crowding;
character and endurance;
haste at work and the strength of the animal.

For the plow to work smoothly, it is necessary to determine the amount of traction force in order to calculate the number of animals for work. This takes into account not only the width and depth of the layer, but also the qualitative composition of the soil.

Plowing with a horse plow using a walk-behind tractor

Today, the walk-behind tractor is an indispensable “iron friend” for many farmers and summer residents. The plow is attached to the walk-behind tractor with a hooking device. After which it is necessary to balance its work. To do this, make a control pass in first gear and look at the depth of the furrow (15-20 cm), and whether the tiller is correctly secured and adjusted.

For heavy walk-behind tractors, a plow with a 23 cm grip is suitable.
For medium walk-behind tractors, a plow with a grip of 18 cm is suitable.

Plowing with a walk-behind tractor is not difficult, the main thing to remember is that the plow always pulls to the left, so the first row must be marked with markings. In the second aisle you will be able to navigate along the first row. The distance between the ridges should not exceed 10 cm.

Universal horse-drawn plow for walk-behind tractor and horse-drawn carriage

When adjusted correctly, the unit moves smoothly, without jerking or deviation to the side. Only after the furrows begin to turn out smooth can the speed be increased.

Setting up a plow on a walk-behind tractor

If the area to be plowed is large, carry out this process in several stages to avoid overheating the engine.

How to make a plow for a mini tractor with your own hands

Making a plow with your own hands will be a good option for those gardeners who want to save money. The equipment is made from materials already available on the farm; parts from old agricultural machinery are suitable.

A homemade plow for a mini tractor is good because it is created taking into account the type of soil on the site. When manufacturing the unit, the crops that will be grown on the land are taken into account. If necessary, different types of plows can be made for different areas.

Store-bought products often require modification, but a homemade product does not have many disadvantages.

The design, made of high-quality materials, does not require reinforcement. Due to the fact that the product is made from parts that are already in the household, it is possible to reduce costs.

Drawings of a plow for a walk-behind tractor

Using the experience of craftsmen who made a plow for a walk-behind tractor with their own hands and left drawings, the ploughshare should be made in such a way that it can be removed, this will make it easier to sharpen it before plowing.

Alloy steel 9ХС, from which I make blades for hand saws, is considered an ideal material for the cutting part of a plow.

Suitable steel grade 45, when hardened, brought to a hardness of HRC 50-55. If you only have ordinary steel on hand, say carbon St5ps, which is not subject to heat treatment, then by beating the cutting edge on an anvil and sharpening it, it is quite suitable for cultivating the soil.

Plow blade for walk-behind tractor

The moldboard of the plow is the part that takes the earth to the side.

The first method of making a blade:

The working surface of the blade must be given a curved shape. If you have a metal bending machine or sheet bending rollers, then giving the workpiece the desired shape will not be difficult.

A metal blank with a thickness of 3-5 mm is required, the rollers are directed at an angle of 20-22 degrees, as shown in the drawing, and the desired bend is given.

Second way:

Here, prepared. A pipe with a diameter of 600-650 mm can serve (this is the diameter that will require less labor, since the bend of the pipe will maximally repeat the desired bend of the future dump) and a thickness of 3-5 mm. We make a template from cardboard and apply it to the pipe, not forgetting the angle of 20-22 degrees, as shown in the drawing below.

We outline the template with a pencil or chalk and cut it out using gas. welding, if necessary, grind the workpiece and bring it to the desired condition.

Third way:

Probably the most difficult method of making a moldboard is when the workpiece is heated and, using a matrix, given the desired shape, which can be a moldboard from another plow.

The material of the plow body is steel sheet grade St3 - St10 with a thickness of 3 mm.

Drawing of plow parts for walk-behind tractor

a — ploughshare made of alloy steel;

b — side shield of the rack, St3;

c — spacer plate, St3;

g — plow base plate, St3;

d - field board, corner 30x30 mm;

e - stand, pipe with a diameter of 42 mm

We advise you to first make the plow parts from cardboard and attach them to each other at the required angles. Thus, the values of the angle α on different parts of the plow body will be from 25° to 130°, the values of the angle γ - from 42° to 50°. If the homemade model of a cardboard plow suits you in all respects, you can move on to working with metal.

When the metal parts of the plow are ready, you need to find an additional sheet of steel 3 mm thick, 600x600 mm in size, it will be needed to assemble the plow, and a welding machine (preferably an inverter). On this sheet we retreat 40 mm from the edges and measure the angle γ0.

Plow assembly

1 - ploughshare;

2 — side shield of the rack;

3 - additional sheet 2-3 mm

Using wedges with an angle α0=25 degrees and an angle γ0=42 degrees, a ploughshare is installed on the additional sheet and tacked to the sheet by welding, pointwise on both sides.

The side shield of the rack is connected to the ploughshare vertically so that its edge extends beyond the ploughshare by 4-7 mm, while the raised shield should be higher than the blade of the ploughshare (that is, higher than the additional sheet) by 6-8 mm, so as not to interfere with the ploughshare, cut the ground. The shield is also attached to the ploughshare and to the additional sheet.

Next, the blade is attached to the ploughshare very tightly, without leaving a gap, so that their surfaces are one whole. The angle between the upper edge of the blade and the ploughshare blade is equal to (γmax − γ0) = 6-8°.

Mounting the plow share

- ploughshare;

— countersunk head screw M8;

- dump;

— base plate;

— corner 30x30x90 mm;

- M8 nut

If it is found that the corners and/or surfaces do not correspond, the blade is adjusted using a hammer. After fitting the blade to the ploughshare, it is welded from the back to the ploughshare and to the side shield. Then the side shield is welded to the spacer bar and the base plate; the thrust corners for the ploughshare are attached to the latter by welding.

Followed by. Inspect the finished plow again, and if everything is clearly welded completely. Add. the sheet is separated from the body with a chisel or LNA. All welds are ground.

How to set up a plow on a mini tractor

After the unit is installed, we begin to configure it. Adjustment of the plow on a mini tractor must be done. Each element should be checked and lubricated with oil. Carefully inspect the wheels on the plow, tighten the screws on all structural elements.

You can set up the plow yourself. It is necessary to check each fastening and adjust the angle of rotation. If the unit will be used on heavy soils, it must be weighted. This is done by installing a metal disk, it is mounted on the frame. In order to properly adjust the product, do the following:

Adjust the depth. There is a bolt on the outer part of the pipe that allows you to adjust the wheels. If you turn it clockwise, the depth of tillage will be increased.
Adjust the width of the land.
Adjust the frame level. To do this, tighten the front bar or stretch it.

Additional equipment can be attached to the plow. Mounting devices used for cultivating land can be done on your own. If the elements are installed incorrectly, the plow will not work well on the ground.

Assembling a homemade product

After all the elements of the future plow are ready, to complete the work you will need a 0.5 x 0.5 m metal sheet and a welding inverter. The plow parts are welded to the workpiece with certain angular dimensions: the plow and the side shield. The moldboard part is applied to the surface of the ploughshare.

If the angles are calculated incorrectly, the plow blade is brought to the correct shape using a hammer, and then it is attached to the back of the ploughshare and to the side shield by welding. Afterwards, an expansion bar and a base in the form of a plate are installed on the shield, on which the corners for the ploughshare are attached.

The assembled home-made product for tillage is carefully inspected for all welded joints and, if there are no defects, all seams are finally welded.

Upon completion of the assembly and welding work, the auxiliary sheet is removed using an angle grinder or available metalworking tools. Places of welded joints require mandatory cleaning, and the blade and ploughshare are treated with sandpaper for standard roughness.

To set the product in motion, it must be attached to a walk-behind tractor. A similar design can be used when constructing a plow for mini tractors. The difference will only be in overall and geometric dimensions, depending on what type of mini tractor the product is designed for.

Building a plow with your own hands, in addition to acquiring certain skills, will significantly help reduce the labor intensity when working on your site.

In order to sharpen blades, it is not necessary to contact specialized organizations. It is enough to use a sharpening stone for this purpose.

While working on the site, soil may stick to the unit. It increases resistance, so it should be cleaned off the blade. You should do the same with plant roots.

When working in the field, it is necessary to lubricate the bearings daily. This increases the service life of the unit. After completion of processing, the plow is washed, dried and lubricated with oil, protecting the product from corrosion.

Agriculture has become a profitable business using modern technology. To grow first and then harvest is the true goal of a farmer. Compliance with technology and endless work is the key to obtaining results.

Among the necessary, mandatory tools, the plow remains, since it allows you to work with different crops; every good farmer needs it. A really good farmer can make a plow for a mini tractor with his own hands, if only he puts in the effort.

Good plow for private farming

A good plow is needed in every farm where a lot of land is cultivated. Of course, such a device can be purchased by paying a considerable amount of money, but not every farmer can afford such an expensive purchase. At the same time, buying a plow is not very rational, since the owner will use it very rarely. Of course, the advantage is that you can plow a small field and spend very little money and fuel if you have a small mini-tractor with a plow.

If the farmer does not have a lot of capital, then the right and correct decision would be to make attachments for his unit with his own hands at a minimum cost. It will not be difficult for a person who knows how to do things on his own to do this kind of work. You just need to choose a good and durable material that would be suitable for this type of work, spare parts for plows, and follow all the instructions in the instructions and rules, in general, nothing complicated. Most people think that it is very difficult and time-consuming to make a plow for a mini tractor yourself. Unsuccessful projects are just poor knowledge of simple geometry among masters who are just beginning their journey. The picture shows a diagram of the development of a drawing for calculating a double-furrow plow for a mini tractor.

To achieve a good result, you need, first of all, skill, and at home it will be difficult to do any thing, since the necessary materials and tools are not always available. There are also different plow models, for example, double-furrow, reversible, rotary. Each option requires a special design and well-selected material; the tools that will be needed when working on the unit are also important.

The shape that is inherent in a plow on a mini tractor

For proper entry into the soil, this attachment, made of metal, is wedge-shaped with an angle specifically required for entry into the ground. A plow for a mini tractor must have consistent parameters for the work for which it is intended. A plow made correctly, according to all the rules and drawings, will serve no worse than its factory counterpart.

First, you need a model; to make it, a drawing of a plow for a mini tractor will help, then you need to make an exact template. The template will be a cardboard cutout of your device for a mini tractor. After the cardboard parts are made, they are assembled. If the design is correct, correct, you need to do the same according to the diagram, only, of course, from metal. This will help the manufacturer avoid mistakes when starting to manufacture a home-made unit.

What blanks are needed to make a plow?

The production of a plow (the process itself) consists of several stages. To create equipment you need materials and equipment:

Rollers;

Metal scissors;

Iron welding machine;

High quality steel tube (diameter 600mm);

Several sets of nut-screw (M8);

Alloy steel 9ХС (5mm);

Metal sheet (3 mm, 50*50 cm);

If you want a rotary plow model for a mini tractor, then you need to start working on it only after watching an instructional video or consulting with a knowledgeable person. For the agricultural sector, the most popular ones are: double-body, single-body (rotary), reversible. The picture shows the model of the rotary version; it is the simplest and is very inferior to other analogues of the unit.

Single body plow model

First you need to make an oval cylinder shape. Parts for assembly: side shield of the rack, additional sheet, plowshare. To install the ploughshare, you need to insert the wedges onto the sheet at an acute angle of 45 degrees, then the surface of the ploughshare must be connected to the side shield, while the blade of the ploughshare itself must protrude 1 cm below the shield. Next, the blade must be attached to the ploughshare, then we weld everything to the plow welding

Rotary plow model

You can make a reversible plow for a mini tractor with your own hands according to the principle of a trailer. For convenience when cornering, this model has a grip. A reversible plow will allow the minitractor to make even furrows; with each subsequent pass there is no need to return to the other end of the site, since reversing the plow will turn the furrow in the opposite direction.

The reversible plow model consists of three parts:

• Lower horizontal plane of the runner;

• Front blade plane.

The edge that will be cut must be positioned 2 cm below the runner, and the edge of the ploughshare and the side edge of the blade must converge. It is necessary that the ploughshare leans against the blade without gaps, very tightly. If such a model is put together, then you can weld all the structural elements together and be confidently satisfied with the result.

Dimensions

The dimensions of different types of plows may vary. You can consider the parameters of parts using the example of a rotary specimen. It is taken into account that the rotary type of such a device is assembled from the following bases:

side vertical part of the runner;
horizontal plane below the skid;
front dump part.

The most productive is considered to be a plow in which the cutting edge at the bottom of the fixed share is 20 mm below the bottom of the horizontal skid. Another correctly aligned part of the plow is the matching of the cutting edge on the side of the fixed share with the cutting edge on the side of the moldboard. The share and blade should not protrude more than 10 mm beyond the boundaries of the vertical plane on the side of the skid.

There is one more important nuance - fastening the front plane of the blade share without visible cracks and gaps, and in the same plane. If we look at these parts in more detail, they should be well polished and, like a mirror, reflect any surface. There should be no protruding fasteners under any circumstances. As soon as the plow returns from earthworks, it is advisable to clean it of settled soil and foreign particles. Elements that have been polished should be poured with oil or coated with grease. Next, the mechanisms need to be rubbed using a rag. In this way, it will be possible to protect the structure from aggressive external influences, which can lead to the formation of corrosion on the surface of the plow.

As for the 4th correctly constructed structure, it includes the flat front surface of the ploughshare, which makes an angle of 20 degrees with the flat part of the plow structure. It will be equal to the angle located at the rear of the exposed share. The cutting sidewalls-edges of the plowshare and blade will also have 20-degree angles with their bases on the side of the furrow. Moreover, the edge located on the side of the blade may be slightly rounded.
